Drive Letter - Add, Change, or Remove in Windows

Just trying to fill in the fields, and not being technical, that’s as much info as I can provide!

Thank you Brink, for this excellent tutorial! I am managing a large number of touch-screen kiosks running Win 7. Program is on thumb drives, updated annually and must run on F. Users are (by and large) not computer-savvy. I can step them through Disk Management....but some units have "phantom" drive on F that is blocking changing in Disk Management. I believe stepping them through regedit is too risky. Is there a way to create a .reg file that would delete references to E, F, G, etc. (everything other than C and D)?

Thank you so much, Shawn. This will be a huge help!

THANK YOU FOR SAVING ME A LOT OF TROUBLE.
FOLLOWED YOUR ADVICE TO CHANGE DRIVE LETTERS, TYPED INSTRUCTIONS AND FOUND DOS.
I HAD TO RE INSTALL WINDOWS AND THE DRIVE LETTER BECAME B INSTEAD OF D COULD NOT CHANGE TO D,AS I FOUND OUT IT WAS ALL READY IN REG SO FOUND D DRIVE DEL IT AND CHANGED LETTER TO D AND THAT WAS IT.
IF I CAN DO IT ANYONE CAN.
SOLVED

Just did a clean install of Windows 8 and no longer found my secondary HDD listed in file explorer. Never knew about the diskpart program until now. Thank you, very much.

Thought I might post here since my problem began after following these same steps. Apologies if I'm mistaken

I've been running an SSD on which the OS is installed (Win7 Home Premium), and I'm using an HDD for data storage. All programs are on the SSD. I've been using the system without problems for about a year, except that windows search never returned ANY results on the storage drive. I exhausted all indexing solutions many times and had given up, figuring I'd just live with it. Then I encountered a post by someone with the same setup as mine who had the same problem, and they immediately solved it by changing their storage drive from B: to something else. So I successfully changed the B: to an S: drive, per your tutorial and the search function was restored.

However, the problem was that after I restarted, all but the recycle bin was gone from my desktop, and I received persistent error messages similar to:

"B:\Windows\system32\config\systemprofile\Desktop refers to a location that is unavailable. It could be on a hard drive on this computer, or on a network. Check to make sure that the disk is properly inserted, or that you are connected to the Internet or your network, and then try again. If it still cannot be located, the information might have been moved to a different location."

Note: I'm not 100% certain that the filepath above (in red) was precisely the filepath shown in MY error, but I do believe it referenced the desktop. I AM certain however, that it referred to the B: drive that I had just changed to S:

I was able to access all programs (at least all those attempted) just fine by using the start menu, but again, the desktop was completely empty but for the recycle bin. Apparently the download folder (which also had pointed to the B: drive) was also affected, as I could no longer access the downloads using the links to downloads that displays in my web browser. As I test, I attempted to download a program update, but it was unresponsive and didn't seem to download at all (I assume due to the old B: filepath). Incidentally I was able to access all my data normally, as I had before, via Windows Explorer.

I was unable to find a quick solution, so I re-named the storage drive back to B:, and all but the Windows search function works-- just as it did in the first place. However I'd like to rename it again to S: so I can use Windows search, but how can I restore my desktop, download folder, and who knows what other links the drive change severed?

Thanks in advance-
